Read the excerpt from marian anderson’s “gifts of speech.” it is a real privilege to greet you and tell you in this way about changing patterns for women workers in the united states. […] even a year of war has led to social revolution here. which word best describes anderson’s tone in this excerpt?

The correct answer is the word "enthusiastic", it sets the tone for the excerpt because it denotes gratefulness and awe of the action’s women have done and what they have achieved despite the obstacles they had to face. So basically, the author is glad to be able to speak about the topic with another person.
